Question

I’m giving my first steps on Python. I saw that we don’t have switch case statement, so I would you guys implement a text Menu in python?

Thanks

You might do something like this:

def action1():     pass # put a function here  def action2():     pass # blah blah  def action3():     pass # and so on  def no_such_action():     pass # print a message indicating there's no such action  def main():     actions = {'foo': action1, 'bar': action2, 'baz': action3}     while True:         print_menu()         selection = raw_input('Your selection: ')         if 'quit' == selection:             return         toDo = actions.get(selection, no_such_action)         toDo()  if __name__ == '__main__':     main() 

This puts all your possible actions’ functions into a dictionary, with the key being what you will input to run the function. It then retrieves the action input action from the list, unless the input action doesn’t exist, in which case it retrieves no_such_action.

After you have a basic understanding of how this works, if you’re considering doing a Serious Business command-line–type application, I would look at the cmd framework for command-line applications.
